CBSE Class 6 Answered
Ellen wanted to buy the following items: A DVD player for Rs 49.95, a DVD holder for Rs 19.95 and a personal stereo for Rs 21.95. Does Ellen have enough money to buy all three items if she has Rs 90 with her?

Expert Answer
The phrase enough money tells us that we need to estimate the sum of the three items. We will estimate the sum by rounding each decimal to the nearest one. We must then compare our estimated sum with Rs 90 to see if she has enough money to buy these items.
No, because rounding each decimal to the nearest one, we get an estimate of Rs 92, and Ellen only has Rs 90 with her.
